Support plate for the passage of systems between two zones with different pressurizations of an aircraft

Abstract

A support plate for the passage of systems between two zones at different pressurizations of an aircraft, in the region of a bulkhead separating the two zones. The support plate comprises a connection plate including at least one retaining element and at least one sealing joint and is provided with a plurality of holes intended for the passage of an assembly of systems which have to pass through said bulkhead.

The invention claimed is: 
     
       1. An aircraft comprising:
 a pressurized zone; 
 a non-pressurized zone; 
 a bulkhead separating the pressurized zone from the non-pressurized zone; and 
 a support plate for the passage of systems between pressurized zone and the non-pressurized zone positioned within an opening in the bulkhead, said support plate comprising:
 a connection plate, 
 said connection plate comprising at least one retaining element and at least one sealing joint arranged on the periphery of at least one face of the connection plate, 
 said connection plate further comprising at least one electrical connector and at least one hydraulic connector passing through the opening in said bulkhead, and 
 wherein said retaining element is provided with two branches, of which one is intended to come to contact with a face of the connection plate and of which the other is suitable for being fixed on a structural element. 
 
 
     
     
       2. The aircraft according to  claim 1 , wherein said sealing joint is arranged on a face of the connection plate which is subject to the lower pressure. 
     
     
       3. The aircraft according to  claim 1 , wherein said sealing joint has a U-shaped cross-section. 
     
     
       4. The aircraft according to  claim 1 , wherein said sealing joint is integrated in the connection plate. 
     
     
       5. The aircraft according to  claim 1 , wherein said connection plate has the shape of a right-angled triangle with rounded corners and a side opposite the right angle corner which is slightly curved with a convex shape. 
     
     
       6. An aircraft comprising:
 a pressurized zone; 
 a non-pressurized zone; 
 a bulkhead separating the pressurized zone from the non-pressurized zone; 
 a support plate for the passage of systems between pressurized zone and the non-pressurized zone positioned within an opening in the bulkhead, said support plate comprising:
 a connection plate, 
 said connection plate comprising at least one retaining element and at least one sealing joint arranged on the periphery of at least one face of the connection plate, 
 said connection plate further comprising at least one electrical connector and at least one hydraulic connector passing through said connection plate from the pressurized zone to the non-pressurized zone, and 
 wherein said retaining element is provided with two branches, of which one is intended to come to contact with a face of the connection plate and of which the other is suitable for being fixed on a structural element. 
 
 
     
     
       7. The aircraft according to  claim 6 , wherein said retaining element is fixed by one of its branches to a structural element rigidly connected to the bulkhead. 
     
     
       8. The aircraft bulkhead according to  claim 7 , wherein said structural element is a base of which the internal periphery is adapted to the external periphery of said connection plate so as to allow sliding thereof.
